A designer wants to reduce print time but keep wall thickness constant. Which adjustment is best?
AIncrease layer height and reduce perimeters
BIncrease nozzle width and reduce number of perimeters
CDecrease nozzle width and increase number of perimeters
DReduce print speed and increase perimeters
Step-by-Step Solution
Solution:
  1. Step 1: Understand how wall thickness is maintained

    Wall thickness = Number of perimeters x Nozzle width.
  2. Step 2: Adjust nozzle width and perimeters to keep thickness

    Increasing nozzle width allows fewer perimeters to maintain thickness, reducing print time.
  3. Step 3: Evaluate other options

    Decreasing nozzle width or increasing perimeters increases print time; layer height affects vertical resolution, not wall thickness; print speed affects time but not thickness.
  4. Final Answer:

    Increase nozzle width and reduce number of perimeters -> Option B
  5. Quick Check:

    Thicker extrusion + fewer perimeters = same thickness, less time [OK]
Quick Trick: Bigger nozzle + fewer perimeters keeps thickness, saves time. [OK]
Common Mistakes:
  • Reducing nozzle width to save time
  • Ignoring relationship between nozzle width and perimeters
  • Confusing layer height with wall thickness
